Review on Sun's Tea Double Walled Drinking Glass, Manhattan-Style Glass - Ideal for Hot and Cold Liquids, Whiskey, Bourbon, Vodka, and Scotch - Premium Borosilicate Clear Glass - Set of 2 by Barbara Lawler

I received them a few days ago and I'm totally impressed. I didn't know about double glazing. I bought highball glasses, saw these and decided to give it a try. I like to make whiskey or iced scotch with ice. The problem is that the ice melts quickly and the glass sweats so much that I end up with a puddle of water on my desk and the glass drips on me. So I washed the glasses. Not because they were dirty, but what I always do with new glasses or dishes. Then I filled a glass with ice and poured a few sips of whiskey into it. Here I am an hour later and the jar is still full of ice in a 70 degree room and the outside of the jar is completely dry. Melons, melons, melons, WINNER!
